Reuse an existing Supabase project. This guide covers connecting multiple Rocket projects to the same Supabase database, building new Rocket projects using an existing setup, and understanding when sharing a database makes sense.You need:
  • A Supabase account with at least one active project.
  • Your Supabase account connected to Rocket.
  • Access to the database you want to use.

​
Why share a Supabase database

Sharing a single Supabase project across Rocket apps is useful when you want to:
  • Power multiple frontends (e.g., customer site and admin panel) with the same data.
  • Keep authentication, storage, and APIs consistent across builds.
  • Test new UI designs without duplicating your backend.
Already using Supabase? You can bring that database into Rocket and focus entirely on the UI.

​
Best practices

Rocket connects to your entire Supabase project, but only uses what you tell it to. Clear prompts lead to cleaner builds.
  • Start with your schema In your first prompt, mention the tables and fields you need. Example:
  • Table: Users → Fields: Name, Email, Date joined
  • Table: Orders → Fields: Order ID, Status, Amount
  • Describe your setup If your database is already live, say so. Rocket will not auto-detect the schema unless you explain it.
  • List the pages you want Tell Rocket exactly what you need. Example: “Create a Users page showing Name and Email, and an Orders page showing Status and Amount.”
  • One project, one purpose Keep Rocket projects focused. For example:
  • One for your user-facing app
  • One for your internal dashboard
  • When Rocket generates scripts Only push the script if you want to update the actual database.
  • Push when: You are adding new fields or tables.
  • Do not push when: Your schema already includes everything you need.
  • If multiple apps share the database Database changes affect every connected Rocket project. If one app adds a field, others can access it, but you will need to update those UIs separately.

Example scenario:
  1. In App A, you prompt: “Add a Phone number field to user profiles.”
  2. Supabase now has a new field: Phone number.
  3. App B also connects to this database, but does not yet show the field.
  4. In App B, prompt Rocket: “Update Users page to show Phone number.”
  • Try it in a test project first Exploring ideas? Connect to a test Supabase project before making changes to production.
The more clearly you describe your schema and goals, the better Rocket can build what you need.

Use an existing Supabase project in Rocket

1

Start a new project in Rocket

From your Rocket dashboard, create a new project. Start blank or use a template.You are taken to the Rocket workspace for your new project once it is created.
2

Connect your existing Supabase project

  1. When prompted, choose Supabase as your database provider.
  2. Log in to your Supabase account.
  3. Select the project you want to link from the list.
You can connect to a Supabase project used by another Rocket app or one created outside Rocket.
Rocket confirms your Supabase project is connected.
3

Start building your UI in Rocket

Rocket uses your existing schema, tables, and auth settings. You can now design pages and components without touching the database.Your app shows live data from your Supabase project.

​
Troubleshooting

​
1. I do not see my Supabase project in Rocket

After signing in to Supabase, the project list is empty.
  • Make sure you are signed in to the correct Supabase account.

​
2. Changes in one Rocket project affect another

Updating the database in one Rocket project instantly affects another.
  • This is expected behavior when projects share a database.
  • To isolate changes, connect each Rocket project to a separate Supabase project.

One database, multiple projects

Share data, streamline your builds, and redesign faster by connecting Rocket apps to the same Supabase database.
